 When measuring large forested areas, it is not practical to pull a graduated tape to measure distance through the woods. So, using a calibrated pace is a good alternative. A pace is two steps taken at a comfortable gate, which can be maintained throughout the workday and across a wide range of walking conditions. To determine your pace, measure out one chain, or 66 feet, and mark the starting and ending points. Walk this length several times at a comfortable gate that you can maintain in a variety of conditions and record your results. Average your results to get an estimated number of paces it takes you to walk one chain. That number should probably be between 10 and 15 paces per chain. Each person's pace is different. It can change with age, differences in walking conditions, weather conditions, clothing, and other factors. You should determine your pace under different conditions and know when to use different pace factors. With practice, you can use your paces per chain to estimate distances in the field without using a measuring tape.
